This one to get started: Elements of Abstract and Linear Algebra.

If you write clearly, then your readers may understand your mathematics and conclude that it isn't profound. Worse, a referee may find your errors. Here are some tips for avoiding these awful possibilities. Serious: I learned some new stuff today. Semi-Direct Groups ( at last ) and some first glimpses of Polya Burnside Enumeration.
